Nealyneal Posted September 6, 2021 Report Share Posted September 6, 2021 I am a former pioneer repair tech. Bought a avh4200nex with a blank display. Unit powers up but I put a bad display on the unit and shorted out a fuse on the main board. Just need to know the location to check, thx Quote Link to post Share on other sites

Nealyneal Posted September 7, 2021 Author Report Share Posted September 7, 2021 I dont have the test jigs to lay the boards out and take voltages unfortunately. I guess when the monitor or keyboard are corroded it blows a particular thing. Just need to figure that out, thanks Quote Link to post Share on other sites
